Where I work I very frequently have position dimensions called out in sets. When the DRF is not fully constrained, or when there are MMB modifiers on datums, its critical to call the holes out as sets so any Datum Shift is the same for all the holes in…
Good Morning! I have this part (shown below) that calls out a slot as the tertiary datum and I am having trouble trying to get the true position to show the MMC to .0002 for the callout for -D-. I am measuring it by taking 1 hit on each side of the slot…
Good Morning! I am still very new to PC-DMIS and I am having trouble with the Xact measurement of a true position callout for a feature. The callout for the hole should read TP/ Ø.005 @ MMC/ A @ MMC but when I try to dimension it, it does not allow me…
All of my FAIRs and FIRs are bubbled such that the True Position and Size are two different bubbles and require two different
labeled dimensional readouts on my reports; thus, I make separate dimensions for size (diameter in this case) and true position…
Hello, in the beginning i want to emphasize that i'm a new use of pc-dmis software (4 months) and worked with the other software (ArcoCad) for 3 years.
Now I'm stuck with one thing in XactMeasure GD&T. I got part that has datums like in the drawing…
I recently ran into an issue when reviewing reports that shows the following for a true position measurement in a CAD view:
I did some digging on both of our CMM stations thinking that one of them may have an oddball setting or a corrupt font…
I have holes that I could only create as single point circles (they are 4-40 threaded holes) that have a true position call out. I created a position dimension and matched the feature control frame to the drawing (using 3 datums) but PC-DMIS reports failure…
Hi,
New guy here. I have a a cast aluminum block with a cored hole that I need to get correct diameter measurement on. The hole is in the shape of a teardrop. Looks exactly like a teardrop.
The hole is currently measured by inserting a gage pin…
Hi,
End of measurements i notice something in the report that actual values have gone back to nominal values.
This has happened on three different things.
1) Constructed circle from a measured cone( here i use height, value, origin, workplane…
When reporting a true position, should the Feature MMC bonus and Datum LMC bonus be added together, to give a an overall bonus.
Pc-Dmis defaults to adding the bonuses. Is this correct ?
The drawing call out = TP | (DIAMETRIC) 0.004 (MMC) | DATUM…
dear all,
I am new guy for PCDMIS, currently I am using PC-DMIS rev 4.3 and 2012.
recently, I found a problem with a program for my product. it is about a true position of a circle, please refer to attached photo for details.
a circle which is…
I Have trouble when showing True Position on FCF,
There is some information i want to hide or delete, that is location on Datum which shown in Position tab, that information come when i add secondary and tertiery datum with MMC or LMC on True Position…
Can someone please help me figure out the best way to set up an alignment with only 2 datums? The print I am working off only has a datum A plane and a datum b diameter and is wanting some gd&t position information just using A & B instead of the A, B…
So I have looked at every bidirectional TP thread on - I am programming for a customer with 2011 MR1, so width is out of the question (and has been flaky at best in 2014.1).
With only a few years experience, I was never taught constructing generic…
Can someone please explain what the Arrow Multiplier in the Advanced Tab of the True Position Xact Measure window does? I had it set for 10, and it caused no problems. But in the program I just wrote, I was getting True Positions that made no sense, so…
I am running a part we had programmed outside about a year ago before my time. There is TP of the mid-point of two planes. I have searched high and low (and maybe I am missing something a simple constructing/dimensioning move), but cannot find a reason…
Hello all.
I have one problem with reporting TP which have for nominal an angle and distance.
is this even possible in PC-DMIS?
In the attach photo you can see what is the problem.
Datum A is circle, B is frontal plane and C is small plane inside…
I'm runing 2014.1 (Service Pack 4)
I set over a big magnet 30 parts in a equally spaced grid 25 mm X = 5 parts and Y = 6 parts (see loop code)
Problem: True position part # 1 measure 0,0. Part # 2 measure 50.0. Part # 3 measure 100 so on.
Can anyone…
When I am calling out a true position of a feature and I use a datum with a MMC a Ø symbol appears. Do I put in the MMC of that datum or will pc-dmis figure that out for me by using the tolerances I give it? Thank you.

Hi guys,
Basically I'm measuring a bunch of parts for a capability study. Long story short I need to get true position on four similar features. For this instance I'm not sure how to accurately pull this off with the feature inside PC-DMIS since I…
Opinion needed:
Was wondering if it was possible for one of these holes (dat-c-) to give good t.p readings. Since the parts is symmetrical all 3 holes should be used with dat-a- for an alignment (a-c in feature control frame). So it would be possible…
I have been running into problems using 2014 where it seems like I am getting a backlog of information being used when it shouldn't be. Example: I program a part, very straight forward alignment, A-top plane, B- Line, C-cylinder...theses are used for…
hello there! so i've been having problems fixing this true position dimension. say the part location, on x and y are 1.0 x 1.0 true position of .005. but if my nominal says its 1.005 x 1.007 and i can't change that! because my actual readings are of 1…
Hello,
I am trying to create a true position command using FCF. I have a MMC on Datum B. Datum A is the surface perpendicular to the hole and Datum B is the OD of a part with various holes on a Bolt Circle. I set up the true position and add maximum…
